EVAPORATION APPARATUS FOR IMPROVING THE AIR The present inventionrelates to an evaporation apparatus for improving the air, which isprovided with a felt plate for the evaporation fluid and has pipe meanson opposite sides of the felt plate which are surrounded by cone-shapedguiding ribs of varying diameter so that said guide ribs have adoublecone contour. The said guide ribs are interconnected byplane-supporting ribs and are, through the latter, also connected to thesaid pipe means forming an axial pipe member. The apparatus also has aholding ring arranged between the two conical guide rib structures andprovided with openings. The evaporation apparatus is intended forimproving the air in industrial plants, toilets and the like.

An evaporation apparatus for air improvement equipped with a felt platefor the evaporation fluid has become known.

Such apparatus has an axial pipe structure around which coneshapedguiding ribs of difl'erent diameters are arranged in a double-conedesign. In the center of the double-cone design there is provided thefelt plate while between the two conical structures there is arranged aholding ring provided with bores.

It is an object of the present invention to provide an evaporationapparatus for air improvement which is provided with a felt plate forthe evaporating fluid and has pipe means arranged on opposite sides ofthe felt plate.

More specifically, it is an object of the present invention to providean evaporation apparatus as mentioned in the preceding paragraph whichcan easily be mounted in difierent ways and can easily be opened andclosed for exchanging the felt disc.

These and other objects and advantages of the invention will appear moreclearly from the following specification in connection with theaccompanying drawing, in which:

FIG. 1 diagrammatically illustrates the evaporation apparatus accordingto the invention as separated from the baseplate, partially in view andpartially in section along the line I-l of FIG. 2.

FIG. 2 is a top view of the lower half of the evaporation apparatusaccording to the invention with mounted-on and locked baseplate in crosssection.

The apparatus according to the present invention is characterizedprimarily in that the holding ring is in a direction transverse to itsaxial direction and in the central area divided while each section isconnected to'the supporting ribs of the cone and is connectable to theother section by a clamping arrangement. Each section carries twoparallel pronglike tongues adapted to be inserted into a smoothbaseplate and connectable thereto. in this way, the holding ring forms apart of the construction of the evaporation apparatus so that it doesnot form a loose member which has to be designed in conformity with theother elements in order to fit.

In addition to the baseplate, the apparatus according to the inventioncomprises only two substantially identical parts, which fact greatlyimproves the manufacture and stockkeeping of the apparatus and partsthereof. The baseplate oflers the possibility of connecting theevaporation apparatus temporarily or permanently to a wall surface.After the permanent connection of the baseplate, the evaporationapparatus is adapted by means of said prong-shaped tongues easily to bedetached from the baseplate or to be connected thereto.

For connection of the apparatus according to the invention to thebaseplate, the said tongues have those edges thereof which face eachother provided with a recess which combines to an opening adapted to beengaged by an elastic member adapted to interlock with the baseplate.

For purposes of permitting detachment of the evaporation apparatus,according to the invention, from the baseplate, the baseplate is, forreleasing said locking member on each side, provided with a recess whichpermits access from the outside to said locking member.

In order to be able selectively to connect the baseplate temporarily orpermanently to a wall, the baseplate is provided with a bore, twosuction fasteners and has its back side provided with pressedon,self-sticking tapes. For protecting the self-sticking tapes or bands,the baseplate has its rear side provided with four spacer means adaptedto be cut off.

Advantageously, the two sections of the holding rings are provided witha spring and a groove forming the clamping closure means. 7

Referring now to the drawing in detail, the apparatus illustratedtherein comprises two cones l and 2 mounted in such a way as together toform a double cone. Said cones extend around an axial pipe 3 and 4respectively. Each cone comprises conical guiding ribs 5, 6respectively, of varying diameter and arranged in the manner of stairs.The upper guiding ribs 5 are flaring upwardly and the guiding ribs 6 areflaring downwardly. The guiding ribs 5, 6 of each cone are held by asupporting star member 7, 8 comprising six supporting ribs. The guidingribs 5 and 6 are injection molded and consist of one single piece of anysuitable synthetic material with the supporting star members 7, 8. Thesupporting ribs of the two members 7, 8 are fixedly connected at theirouter edges 7a, 8a with a portion 9a and 9b of a circular holding ring9. At those of their edges which face each other, the two sections 90,9b of the holding ring 9 have one-half thereof provided with a spring 16and another half provided with a groove 17. These members form aclamping closure arrangement which holds the two sections 9a, 9b of theholding ring 9 together after they have been assembled. The holding ring9 is completely provided with openings 10 in order to obtain a lateralair entrance.

In the interior of the apparatus according to the invention there isprovided a felt plate 11 which has bores Ila.

The axial pipes 3 and 4 are closed by stoppers I2, 13 respectively. Theupper stopper 12 is detachable in order to permit the evaporation liquidto flow through the pipe 3 of the felt plate 11. The lower stopper [3may be inserted permanently into the pipe 4.

In view of the double-conical design, the air entering the apparatusfrom below will be directed in the direction toward the felt plate forthe evaporation liquid. In view of the evaporation, an airflow in upwarddirection will be created. This airflow will be passed through the upperconically arranged guiding ribs. Thus the evaporation apparatus ispassed through by air from the bottom toward the top.

The circumference of the two sections 9a and 9b of the holding ring 9has fixedly arranged thereon two insertable tongues l4 and 15 which, atthose edges that face each other, are respectively provided with arecess 14a and 15a, said recesses together forming an opening l8. Thetongues 14 and 15 located in one plane are insertable in two pockets 19of a smooth baseplate 20. These pockets 19 have their inner wallprovided with an opening 22 from which an elastic member 23 is formedwhich is bent at an incline toward the outside. When inserting the saidtongues l4, 15 into the pockets 19 of the baseplate 20, the said members23 are first by the outer edges of said tongues elastically pressedinwardly. After the tongues have been completely inserted into thepockets 19, they will, due to their own elasticity, spring into theopenings 18 of the tongues and have their end faces rest before theouter edge of the openings 18. The evaporation apparatus and thebaseplate are now permanently connected to each other.

For purposes of detaching the apparatus from the baseplate 20, the outerwalls of the pockets 19 are provided with recesses 24 through which themember 23 can be pressed inwardly to such an extent that it leaves theopening 18 and the tongues 14, I5 can be withdrawn from the pockets 19.

The baseplate 20 is smooth and. for purposes of a temporary connectionto a wall surface, is provided with suction cups 25 of which the upperone can also be pulled out from its holding opening in the baseplate.The baseplate with the evaporation apparatus is then suspended on a hookby means of the holding opening. For permanent connection, the rear sideof the baseplate 20 has two self-sticking tapes or hands 26 pressedthereon which, after withdrawal of a protective foil,

can be pressed against the wall surface. Before this is effected,however, four members 27 have to be arranged on the rear side of thebaseplate 20 and previously forming spacer means for protecting theselfsticking bands have to be cut off smooth. Finally, in the center ofthe baseplate 20 there is provided a screw hole 28 for permanentconnection of the baseplate to a wall surface.

It is, of course, to be understood that the present invention is, by nomeans, limited to the particular construction shown in the drawing butalso comprises any modifications within the scope of the appendedclaims.
